i rw rMamh 18,1938 I a 4 clai s, "(01. 220 40) 1 This invention relates to connecting means, and is concerned more particularly with a novel conjars, or the like made ofmaterials including glass,

eaithenware,"metal, cardboard, etc., adaptations of the invention to those uses will be illustrated anddescribed in detail for purposes of explanation. It is to'be understood, however, and will be at once appreciated that the utility of the invention is not limited to those specific examples.

In utilizing the invention in connection'with a vessel or container to be closed by a cover or lid,

one of the component parts," for example, the J tainer I having a. closure 2 held in place'by the body of the vessel, is provided with a circumferential flange or bead against which the lid or cover is seated, either directly or with a packinginterposed. The two parts are then secured together by means of a metal sleeve which is connected to the cover and is provided witha series of' tongues which are struck therefrom to extend generally circumferentially and project inwardly so "that they may engage the side of the flange opposite to that with which the cover is engaged. The

desired, or may be connected thereto in any other convenient way, as by having a portion overlying theco'ver; For most purposes, however. the cover is provided with an integral dependingcircumferential flange which'is of sumcient length to extend downbeyond the flange on the body of the vessel and'is'provided with the tongues, the sides of which pass beneath the bodyflange to hold the cover in place. The tongues are so formed that, as the cover is moved into position,

" they pass beneath the body flange with awedging or cam action, thus making it possible to secure the cover firmly in position or to remove it' without severe manual enom At the same time, when the cover is in place,the tongues hold it securely so that the" vessel is tightly closed, and, when a packing isused, may be hermetically sealed.

when the annular portion which is provided with tongues is made in an annular closure,a second series of tongues to be pressedagainst or engage over the edge of-a lid orcover on the container may be provided, the two series of tongues being approximately parallel. This embodiment is-particularly convenient for the coupling of two tube-like parts; each series of tongues being adapted to engage over a flange cn each of the twozparts to be coupled.-
